AT83C5134/35/36

7683B–USB–03/07

Description

AT83C5134/35/36 are high performance ROM versions of the 80C51 single-chip 8-bit

microcontrollers with full speed USB functions.

AT83C5134/35 is pin compatible with AT89C5130A 16-Kbytes In-System Programma-

ble Flash microcontrollers. This allows to use AT89C5130A for development, pre-

production and flexibility, while using AT83C5134/35 for cost reduction in mass produc-

tion. Similarly AT83C5136 is pin compatible with AT89C5131A 32-Kbytes Flash

microcontroller.

AT83C5134/35/36 features a full-speed USB module compatible with the USB specifi-

cations Version 2.0. This module integrates the USB transceivers and the Serial

Interface Engine (SIE) with Digital Phase Locked Loop and 48 MHz clock recovery. USB

Event detection logic (Reset and Suspend/Resume) and FIFO buffers supporting the

mandatory control Endpoint (EP0) and 5 versatile Endpoints (EP1/EP2/EP3/EP4/EP5)

with minimum software overhead are also part of the USB module.

AT83C5134/35/36 retains the features of the Atmel 80C52 with extended ROM cpacity

(8/16/32 Kbytes), 256 bytes of internal RAM, a 4-level interrupt system, two 16-bit

timer/counters (T0/T1), a full duplex enhanced UART (EUART) and an on-chip

oscillator.

In addition, AT83C5134/35/36 has an on-chip expanded RAM of 1024 bytes (ERAM), a

dual- data pointer, a 16-bit up/down Timer (T2), a Programmable Counter Array (PCA),

up to 4 programmable LED current sources, a programmable hardware watchdog and a

power-on reset.

AT83C5134/35/36 has two software-selectable modes of reduced activity for further

reduction in power consumption. In the idle mode the CPU is frozen while the timers, the

serial ports and the interrupt system are still operating. In the power-down mode the

RAM is saved, the peripheral clock is frozen, but the device has full wake-up capability

through USB events or external interrupts.
